Now, TmoNews says that, based on the image below, the Xperia Z will be launched on July 17, alongside two other smartphones, the Windows Phone-running Nokia Lumia 925 and a yet-to-be-unveiled T-Mobile 768, believed to be “a prepaid device backed by Huawei, ZTE or some other manufacturer that releases under T-Mobile branding.”

Pricing details for the Xperia Z isn’t available at this time, although you can expect it to be quite affordable under the contract-free UNcarrier plans – this still ties you down to T-Mobile for up to two years, as you’ll have to pay 24 installments of $20 each in addition to what you’ll initially have to shell out for the handset.

Comparatively, the Nokia Lumia 925 is said to cost $99.99 down, followed by 24 monthly payments of $20 per month. Pricing for the T-Mobile 768 is not mentioned at this time.

The same leaked image shows one more interesting event in T-Mobile’s calendar, the July 14 “Major EIT Release.” The publication speculates that on that date, Phase 2 of the UNcarrier plan will be launched, although it’s not clear what the new phase entails “beyond the [rumored] ‘Simple Choice with No Credit Check’ plan.”

We’ll note that T-Mobile is the only major U.S. carrier preparing to stock the Xperia Z, a flagship device that started selling almost five months ago in certain markets. The handset is already available directly from Sony in America for off-contract purchases, although that may not be ideal for most potential buyers.

In short, the Xperia Z is one of the best Android handsets of the year, featuring a 5-inch display with 1920 x 1080 resolution, 1.5GHz quad-core Snapdragon S4 Pro processor, 2GB of RAM, 16GB of storage, 13.1-megapixel camera, 2.2-megapixel front-facing camera, 4G LTE support, NFC, and Android 4.2.2 Jelly Bean (the update has been recently rolled out). Additionally, the handset is dustproof and water resistant (IP55 and IP57 certifications) – see our review here.
